Be it known that l, THEODOR GRUNDMANN, ot' Milwaukee, in the county of Milwaukee, and State of Wisconsin, have invented a new and improved Apparatus for Making Vinegar; and VI do hereby declare that the following is'o.' full, clear, and exact description thereof, which will enable those skilled in the art to inake and use the same, reference being had to the accompanying drawings, forming part of this specicatioin-in which- Figure 1 is a vertical sectional view of my improved apparatus.

Figure 2 is a plan ortop view ofthe same partly in section.

Similar letters of reference indicate corpesponding parts.

This invention relates to certain iniproveinents on. an apparatus for making vinegar, for which Letters Patent were granted to lne on the 11th day of September, 1866.' Y

The improvements consist in the construction ofthe troughs through which' the liquid, which is to be transformed into vinegar, is passed These troughs are placed on a. perfect level, and are provided 'with vertical walls for detaining the liquid in its passage, and by which the same is made to traverse hundreds of feet in n. trough of from twelve to twenty feet length. lhese troughs are placed one above the other, the upper one serving as coverfor the one below,thus doing away with theelainps und obi/ers for the troughs mentioned i-n my aforesaid'Letters Patent. The troughs communicate with-each other by means of pipes at'oue end of each trough; each of the said pipes being' arranged ou the side opposite to that on which the pipe on the trough above is arranged, so that the liquid will have to pass through -the whole length of' cach trough beforeit can ow into the trough below. For this slow motion of' the liquid is arranged a quick motion of air, provision beingmude that. :t current ofuir may pass above the liquid in each trough.

The object ofthe machineitsclf is the same as that described in my aforesaid Letters Patent.

A represents a dat tank or vat containing the liquid` which is to be transformed into vinegar. B is a box, arranged below the vot A and enclosing the. troughs C C, for the purpose of retaining the heat in the troughs and regulating the draughtof' air. '.lhe troughs C are laid in series, three or more yof which may be arranged in one box B. In each series the troughs are lying perfectly level one above another, communicating with each other by holes, a, in the ends 'of the troughs, as shown; said holes being so arranged that the air rising from below, as wcll :is the liquid entering from above, will have to pass through the, whole length of each trough before they can escupe into the next trough. .Each trough is provided with a series of'vertical plates, b-z, (figs.

.1 and 2,) which aie arranged across the troughs, leaving a space between tbc end ot' the plate I) and the side ot' the trough for the liquid to pass through; ,these spaces being arranged alternately on the opposite side of the. trough to let the liquid pass through the trough in a zigzag line. 'llie plates I1 b are not as high as the troughs, for the purpose of not obstructing the passage of the air. The liquid is conveyed from the vat- A to the'troughs by means of pipes, l), connecting the vat with th,l cover of the box B, whence the liquid is brought to each series of troughs through a separate pipe. One or more holes, c c, are provided in the cover of the box B, which, in connection with the holes dal in the side or bottom of box B, below the lowest trough, keep upthe required circulation of air, which' nniy be regulated by dampers, e, arranged at the holes d. A ppe,f,'provi ded with a funnel-shaped end, serves to convey the heat into the box B. The vinegar is collected from thc lowest troughs in a box, E, and may then bc drawn ed through a pipe, y. i l

By this apparatus the overheating of the air is prevented, as free circulation is provided, but should some` ofthe acid be evaporated, it will be prevented from, escaping by thestrong current of air, and helps to acidity theifresh liquid which enters the troughs from the vat A, If too much phlegni is formed in the upper troughs, i

(the lower ones are always clear of the sauie,) the box B is taken apart, being constructed so that this can be done, and 'the troughs are then removed and cleaned, and operations may again be commenced instantaneously.

I claim as new, and desire to secure by Letters Patentf The arrangement of a series of level troughs, C, provided with holes, a,vth;ough which the liquid to be aciditied, and also'va current of air, are conducted, and provided further with plates b b, whereby the liquid is detained and itscourse lengthened without interrupting the rapid current oi` air, alllmade and operating substan` tially as herein shown and described.

The box B, wherein' the aforesaid troughs are' placed, said box being so arranged that it may be easily taken 'apart and put together, und being provided with holes d and c for creating a circulation of air, and with dempers e for regulating the same, all made and operating substantially 'as herein shown and described.
